Mark 10:8

and the two will become one flesh, so that they are no longer two, but one flesh.

Or don't you know that he who is joined to a prostitute is one body? For, "The two," says he, "will become one flesh."

Therefore a man will leave his father and his mother, and will join with his wife, and they will be one flesh.

Even so husbands also ought to love their own wives as their own bodies. He who loves his own wife loves himself.
